摘要：

Two novel diterpenoids, thecacorins A (1) and B (2), were isolated from Thecacoris batesii and their structures were established as ent-3 beta,20-epoxy-16-kaurene-3 alpha, 12 beta-diol and ent-15-beyerene-,2 beta,3 beta-diol, respectively, on the basis of extensive spectroscopic analysis, especially, 1D NMR spectra, in conjunction with 2D experiments, COSY, NOESY, HMQC and HMBC.
